Product Overview

The Bently Nevada 330851-02-000-070-50-00-05 is a high-precision 25mm proximity probe engineered for large-scale machinery protection systems. Featuring a specialized PEEK tip with a V-0 flammability rating and a 304 stainless steel case, this transducer is built for thermal resilience and chemical resistance.

Technical Configuration

  • Model Number: 330851-02-000-070-50-00-05
  • Sensing Diameter: 25 mm High-Performance Tip
  • Thread Type: M30 x 2 Metric Threads (02)
  • Unthreaded Length: 0 mm Full Thread (000)
  • Case Length: 70 mm Case Length (070)
  • Total Length: 5.0 Meters / 16.4 Feet (50)
  • Armor Option: Standard No Armor (00)
  • Agency Approvals: ATEX, IECEx, CSA Multi-Approval (05)

Technical Specifications

Linear Range 12.7 mm (500 mils) Operating Temp -51°C to +177°C
Dielectric Strength 500V (FluidLoc® Cable) Max Torque 163 N·m (120 lb-ft)
Certification ATEX/IECEx Zone 0, ABS Type Approval, FCC Part 15B

Installation & Maintenance

1. Thermal Management: The 330851-02-000-070-50-00-05 is validated for 200°C continuous operation. Ensure that the PFA cable is routed away from direct contact with surfaces exceeding 250°C to maintain the 500V dielectric insulation strength.

2. Precision Gapping: Use a digital voltmeter to set the probe gap. This 25mm probe is typically calibrated for a -10.0 Vdc center point when used with a 3300 XL 25mm Proximitor. Always verify the target material (standard 4140 steel) before final commission.

3. Electrical Grounding: The triaxial 3-layer shielding requires proper termination at the Proximitor to ensure immunity against 50Hz-1GHz interference as per EN 61000-6-2/4 standards.

Engineering Advantages

Bently Nevada's 25mm proximity systems offer the industry's most reliable solution for measuring shaft displacement on large rotating machinery. The 304 SST case construction provides a rigid 163N·m torque capacity, preventing mechanical deformation during high-stress installations. With ABS Type Approval and 120g shock compliance, the 330851-02-000-070-50-00-05 is equally suited for stationary power plants and demanding marine propulsion applications.

Technical FAQs

Q1: What makes the FluidLoc® cable special?
A1: It is a 75Ω triaxial cable that prevents fluid migration through the cable and provides 3 layers of shielding for superior noise rejection.

Q2: Is this probe compatible with Zone 0 hazardous areas?
A2: Yes, the "05" approval includes ATEX/IECEx ia IIC T1-T5 ratings for safe operation in Zone 0 environments.

Q3: Can I use this probe with a standard 3300 XL 8mm Proximitor?
A3: No. This 25mm probe MUST be paired with a 3300 XL 25mm Proximitor to ensure correct linearity and sensitivity (0.787 V/mm).
